- *
- * buflen=N default N=4096, buffer size used
- * qlen=N default N=32, how many buffers in the loopback queue
- * loopdefault default false, list loopback config first
- *
- * Many drivers will only have one configuration, letting them be much
- * simpler if they also don't support high speed operation (like this

- *
- * The Core Interface Layer provides basic services for accessing and
- * managing the DWC_otg hardware. These services are used by both the
- * Host Controller Driver and the Peripheral Controller Driver.
- *
- * The CIL manages the memory map for the core so that the HCD and PCD
- * don't have to do this separately. It also handles basic tasks like
- * reading/writing the registers and data FIFOs in the controller.
- * Some of the data access functions provide encapsulation of several
- * operations required to perform a task, such as writing multiple
- * registers to start a transfer. Finally, the CIL performs basic
- * services that are not specific to either the host or device modes
- * of operation. These services include management of the OTG Host
- * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
- * Diagnostic API is also provided to allow testing of the controller
- * hardware.
- *
- * The Core Interface Layer has the following requirements:
- * - Provides basic controller operations.
- * - Minimal use of OS services.
- * - The OS services used will be abstracted by using inline functions
- * or macros.

-/** @file
- * The dwc_otg_driver module provides the initialization and cleanup entry
- * points for the DWC_otg driver. This module will be dynamically installed
- * after Linux is booted using the insmod command. When the module is
- * installed, the dwc_otg_driver_init function is called. When the module is
- * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
- *
- * This module also defines a data structure for the dwc_otg_driver, which is
- * used in conjunction with the standard ARM lm_device structure. These
- * structures allow the OTG driver to comply with the standard Linux driver
- * model in which devices and drivers are registered with a bus driver. This
- * has the benefit that Linux can expose attributes of the driver and device
- * in its special sysfs file system. Users can then read or write files in
- * this file system to perform diagnostics on the driver components or the
- * device.

- * from the specifics of the controller by providing an API to the
- * Function Driver.
- *
- * The Peripheral Controller Driver for Linux will implement the
- * Gadget API, so that the existing Gadget drivers can be used.
- * (Gadget Driver is the Linux terminology for a Function Driver.)
- *
- * The Linux Gadget API is defined in the header file
- * <code><linux/usb_gadget.h></code>. The USB EP operations API is
- * defined in the structure <code>usb_ep_ops</code> and the USB
- * Controller API is defined in the structure
- * <code>usb_gadget_ops</code>.
- *
- * An important function of the PCD is managing interrupts generated
- * by the DWC_otg controller. The implementation of the DWC_otg device
- * mode interrupt service routines is in dwc_otg_pcd_intr.c.
- *
- * @todo Add Device Mode test modes (Test J mode, Test K mode, etc).
- * @todo Does it work when the request size is greater than DEPTSIZ
- * transfer size

-/**
- * @file
- *
- * This file contains the data structures for accessing the DWC_otg core registers.
- *
- * The application interfaces with the HS OTG core by reading from and
- * writing to the Control and Status Register (CSR) space through the
- * AHB Slave interface. These registers are 32 bits wide, and the
- * addresses are 32-bit-block aligned.
- * CSRs are classified as follows:
- * - Core Global Registers
- * - Device Mode Registers
- * - Device Global Registers
- * - Device Endpoint Specific Registers
- * - Host Mode Registers
- * - Host Global Registers
- * - Host Port CSRs
- * - Host Channel Specific Registers
- *
- * Only the Core Global registers can be accessed in both Device and
- * Host modes. When the HS OTG core is operating in one mode, either
- * Device or Host, the application must not access registers from the
- * other mode. When the core switches from one mode to another, the
- * registers in the new mode of operation must be reprogrammed as they
- * would be after a power-on reset.
